IMPROVEMENT INRAGKS FOR GARDING-ENGINBS.; i

To ALL WHOM IT. MAY coNcEnN:

-:Beit known that I, LANG Memos, of Lowell, in the county oi' Middlesex, andStateof liilassachusetts,

have invented certain new and useful Improvements in WasteLPreventing Racks for Carding-Machines, ci' ,which the following is afull, clear,'and exact description, reference being had to the accompanying drawings, making* part offthis specicatiomvjn whichi Figure `1 is a longitudinal verticalsection,

.Figure2, a side elevation,- after a portion ofthe frame has been removed.

Figure 3 is an enlarged innerside view of e. detached pulley, k, shown nred in iig. 2, with the cam e, which vactuates thel slotted arm c to oscillate the slats or bars g.'

'Figure is a. central sectionof 'g. 3.

FigureJ-is a side, and ignre an edge view of e. slotted arm, c, considerably enlarged.

Figure 7 shows a side view ot` a'portion of a detached slat or bar, g, with the end'connection H, one of .the

v pivots ka, on which each slat oscillates, and one of the studs 6, by which all the slats are connected together.'

,i Figure 8 shows a small portion of oneofthe semicircular supports, B, 'to` which theoscillating-bars are 4pivoted, with twoof said bars connected by links d, which connect the whole seriesot` bars in the same or a similar manner. l

Figure 9 is a plan or top view of iig. 8. Y This invention consists in a'series of oscillating-slats or bars, g, arranged .beneath and arounrha considerable portion of the xnain cylinderA, or the tumbler, C, of a carding-niachine, and parallel with the axis of each of such cylinders or tuinblers, and so close to the working surface ol' the curd-teeth on such cylinders, that all the wool orrothcr fibrous sub-stance under operation, which-may be thrown oili from such working or cai-ding; cylinders, hycentrifugal force or otherwise, may be caught. up'by said cardteeth and carried forward and thro'uic'gh` the` various operations of the dier'ent-workng parts of the machine. Suspended or supported by suit` able hangers or brackets, attached tothe frame f the carding-machine, and at'each end thereof, are semicird cular supports, B, whichhave holes, h, to receive the pivots a of the-oscillating-bars-g, as clearly shown-in tig. 8. ."ihese supports.v contain a full sei-ies of oscillating-hars, which forma ntovablerack or grate under the main cyli-nlerAand the-tumbler C. Each series of oscillating-bars is connected together at one or both ends by i linksd, which connect with studs, lb, projecting from the ends ofenoh oscillating-'sinner from the end connection, H,`thereoi`. lThe series of oscillatingfbars or slats, beneath ;th'e tuinbler C, is connected with and operated by the action of the oscillating slat's or bars beneath themain cylinder, by means of Aa.,connecting-rofl or. link, D, i showninig 2. The series of oscillating-slatsorv bars beneath the main cylinder is operated -by or receives' its oscillating nio-tion from a slotted arm, c, actuated by an eccentric, e, secured to the inner side of a. pulley, k, en the outer end oi' the eccentric-shatter stud. This stud vis-adjustahlevertically n a slotted'ear, m, pro` jectin-g downward fromone of the supports, Biibut is held irnily to the, ear hy a -nut screwed 'into the-end offl the stud against the back'of the ear. The slotted arm-a is pivoted to the-lower extremity ofthe ear m, and the top end of said arm has a slot, z', to receive one oi' the studs Zz proje'ctingfrom an oscillating-Slat. The pulley ,7c is ,drivenby a band, o, from apulleyon-the shaft of the main cylinder, or Afrom slome other rotating pulley. l When :the pulley lc is rotated, the eccentric, e, isalso rotated within the sllotE of the arrn c, which moves 'or oscillates `the arm, or the tcp end thereof,- connected with. the studb of one slat or bar, and by means of the links 0i and the link or rod-D, all the slats or bars fare oscillated together. other connecting and operating-device or apparatus may be employed to -impart oscillating motion to the slats or bars,y'and connected with any other moving part of the curling-machine, eitherby a belt or band, or bygears arranged to operate the bars. v The slats or' bars may be of any desired thickness, andplaeed at'any convenient or desired distance apart, to allow the dirt to pass between them to the iloorvbencatlnbut'retain'thc ,wool on their top edges. These slats or bars may be made with A-sllaped top edges, or rounded orpat onthe top or'in'ner edges, according to the length of thefibre or staple of the substance or material to be opera-ted upon.

What claim as new, and desire to secure by Letters Patent, is

`1. I claim a, series of slntsor hareng, constructed and operating substantollylhs described, for the purpose set forth. c

2. I claim the link's d, in combintion with the-pivot'ed slats or bars g, as andv for the purpose setvforth.

3. In combinationwvritlil the two series ot' oscillating-bars, the link or rod D, for connecting one series of suchelats ,or bars with the other series of similar bars, and for operating the same, siubstantiell-jr as and for the purpose specified.

4. I claim the eccentric, e, and'sl'otted arm c, or the equivalent thereof, combined with the series of pivoted slats er bers, and rranged to operate the same, in the manner and for the purpose substantially as specified. 5. I claim the end connection H, provided. with a. pivot, a, and stud 6, for connecting and operating the 'sluts or bars, as set forth.
